Abstract
A turf cutting and handling system for the borehole of a golf green cup includes a generally cylindrical hollow barrel with a cutting edge disposed about a lower periphery of the barrel. A manually grippable handle allows the barrel to be drilled into a playing surface of the putting green, and an ejection port allows a cut plug of turf and soil to be removed from the cutting barrel after the cut plug has been moved from a cutting position to a removal position by means of an ejector plunger which is engaged with the lower rotationally sheared surface of the soil which is underlying the grassy portion of the cut plug.
Claims14
A turf cutting and handling system for forming a borehole for setting a golf green cup, comprising:
- a generally cylindrical hollow barrel with a cutting edge disposed about a lower periphery of the barrel;
- a manually grippable handle disposed about an upper portion of said barrel, so as to permit said barrel to be rotated by means of said handle and inserted into the turf of a golf playing surface by a human operator, with the cutting barrel being adapted to be withdrawn from the turf so as to extract a cylindrical plug of turf;
- an ejection port, disposed in said barrel above said cutting edge and below said handle;
- and
- an ejector plunger for pushing the plug of turf extracted by the barrel upwardly in the barrel from a cut position and into registry with said ejection port, thereby permitting manual removal of the turf plug from the ejection port.
A method for cutting a borehole for a golf green cup, comprising the steps of:
- manually rotating and driving a hollow cylindrical cutter barrel, having a depending peripheral cutting edge, through a turf playing surface and into underlying soil, thereby forming a turf plug having a circular grass upper surface, a cut generally cylindrical circumferential surface, and a rotationally sheared soil lower surface;
- manually extracting the cutter loaded with said plug from the playing surface;
- manually sliding the loaded cutter onto an ejection plunger engaged with the lower surface of said turf plug, so as to move the turf plug upward in the barrel until the plug is registered with an ejection port disposed in the cylindrical outer wall of said barrel above said cutting edge;
- and
- manually removing the turf plug from the ejection port.
A turf cutting and handling system for forming a borehole for setting a golf green cup, comprising:
- a generally cylindrical hollow barrel with a cutting edge disposed about a lower periphery of the barrel;
- a manually grippable handle disposed about an upper portion of said barrel, so as to permit said barrel to be reversibly rotated by means of said handle and inserted into the turf and underlying soil of a golf playing surface by a human operator, so as to form a cylindrical turf plug of grass having a grassy end and a rotationally sheared soil end, with the cutting barrel then being withdrawn from the turf so as to extract the turf plug from the playing surface;
- a depth controller for governing the penetration of the barrel into the playing surface;
- an ejection port, disposed in said barrel above said cutting edge and below said handle;
- and
- a closed-end cylindrical ejector plunger for pushing the plug of turf extracted by the barrel upwardly in the barrel from a cut position and into registry with said ejection port, thereby permitting manual removal of the turf plug from the ejection port.
